Replacing Chain today. 5100 miles. It was a little over due according to my chain wear tool. This winter has been pretty hard on my drive train. Maybe I just didn't clean my chain as often as years before. I'm gonna need a new 46t chain ring pretty soon. I'm not looking forward to that since it's 70 bucks. Also I just replaced my bottom bracket from a spindle length of 118mm to 122mm to give a little more distance between the chain and the chain stays.

I also had a blow out a few months ago. The Michelin City tire I had on the back tore right along the bead enough to allow the tube to push through and rupture. I didn't see the problem until I replaced the tube and started pumping up the tire again. This is a good reason to carry a spare tube as will as a patch kit. The patch kit wouldn't have helped me with such a large blow out.
Mid March I rolled Tanager over 5000.

Lately my brakes have been squealing like banshees. I don't know what the deal is. I adjusted the toe-in. I had a shop adjust the toe-in and even went with a different compound. The only two possibilities I can think of are that the brakes have "loosened up" and they flex when applied enough that the toe-in is shifted or that something is getting on the brakes. I'm leaning towards the latter of the two. When I examined the pads today they seemed to have a metallic shine to them and there were a few tiny metallic shavings embedded within. I removed the shavings, lightly sanded the pads and they make no sound while on the stand. I haven't road tested it yet. I think this might be just due to the heavy rain lately. The bike gets really dirty really quick when there's a lot of standing water on the roads. All that grit wears through brake pads pretty fast and I'm sure it's producing some wear on the rims. I'm thinking the metal from the rims mixed with road grit is leaving some sort of residue on the pads. Why I've never had this problem before, I don't know. We'll see if the sound is gone during my commute to work tomorrow and if it comes back during more fair weather riding.
